Short-term effect of therapeutic shoeing on severity of lameness in horses with chronic laminitis.

The research investigates the immediate impact of four different therapeutic shoeing systems on horses suffering from a chronic hoof disease called laminitis. It concludes that none of the treatments made a significant difference to the severity of lameness in the short-term, suggesting that improvement might not be visible within the first week.

Study Design and Methodology

This study involved ten horses suffering from chronic laminitis. The researchers examined the effectiveness of four therapeutic shoeing techniques in relieving the chronic lameness of these horses. The methods involved:

• A standard flat shoe
• Fullered egg-bar shoe
• Heart-bar shoe
• Modified equine digital support system

These shoeing modalities were studied using a clinical trial method which involves a concurrent control, crossover design. This means each horse was used as its own control, trying out each shoeing system, to compare and determine which was most effective.

Evaluation of Treatment Success

The success of each shoeing technique was assessed over a seven-day period. The researchers made subjective evaluations based on the Obel grade and clinical scores. These are common scales used for assessing the severity of lameness in horses. Objective evaluations involved the collection of force-plate data, which essentially measures how much pressure the horses put on their hooves when they step.

Results of the Study

The results of this study found that there were no significant changes in the lameness severity of the horses throughout the entire course of the experiment. There were no noteworthy differences between the pretreatment and post-treatment assessments, indicating that the condition of the horses didn’t change significantly over the duration of the experiment, irrespective of the type of shoeing technique used.

Conclusions and Implications

Based on these findings, the researchers concluded that the therapeutic shoeing techniques tested in this study should not be expected to bring about significant improvements within the first week of treatment. They also suggested that perhaps using the severity of lameness as the only measure of therapeutic success may not be a valid approach, implying a need to consider other evaluation criteria or a longer period of treatment to truly gauge the effectiveness of a particular shoeing system.
